When you stir a spoonful of sugar into a glass of water, you are forming a solution. This type of liquid solution is composed of a solid solute, which is the sugar, and a liquid solvent, which is the water. As the sugar molecules spread evenly throughout the water, the sugar dissolves.Mixing a liquid in a gas makes another type of solution, called a gaseous solution. An example of this type of solution is humidity. Humidity is water (a liquid) dissolved in air (a gas).Standard ProcedureThink about how a sugar cube dissolves in water, compared to a package of loose sugar. The cube dissolves more slowly because fewer sugar molecules are initially in contact with the water.In a solid solution, such as sterling silver, copper that has been heated at high temperatures is mixed with silver that also has been heated until it melts. The copper is the solute, which is the substance that will dissolve into the solvent. The silver is the solvent.
